Mesoporous Layered Graphene Oxide/Fe3O4/C3N3S3 Polymer Hybrids for Rapid Removal of Pb2+ and Cd2+ from Water.

ABSTRACT: Mesoporous layered magnetic hybrid GFP2 composed of C3N3S3 polymers, Fe3O4 nanoparticles (Fe3O4 NPs), and graphene oxide with a mesoporous layered "sandwich"-like structure was successfully explored by in situ simple polymerization tactic for rapid removal of Pb2+ and Cd2+ from water. It shows good selectivity and high adsorption capacity (277.78 and 49.75 mg/g) for Pb2+ and Cd2+, respectively. It exhibits the fast adsorption kinetics (>80% elimination efficiency in less than 30 min). The Langmuir isotherm model based on typical monomolecular layer adsorption fits better with the data of adsorption than the Freundlich isotherm model. The adsorption process of GFP2 for Pb2+ and Cd2+ can be explained well with the pseudo-second-order kinetics model. GFP2 is a kind of recyclable solid absorbent, which is an excellent candidate in the heavy metal wastewater treatment. More importantly, GFP2 was set with Fe3O4 NPs which makes it easily separable from wastewater with an extra magnet.
